Im looking at buying a Benjamin gun, most likely a Marauder but the Akela is appealing also. People talk a lot about adjusting hammers and installing regulators and so on. What have you guys done to yours? If I did buy one what should be first on the list to change? What can I change to make it a better gun? I'm pretty good at working with my hands (as long as I have proper instructions) so im not worried about anything being too difficult.
